App Development of Ultrasonic Horn Design Based on Comsol

Abstract

Taking the longitudinal vibration conical ultrasonic horn as an example, this paper used the finite element software COMSOL to complete the design processes which included parametric modeling, modal analysis, harmonic response analysis and app development. The errors of modal analysis and harmonic response analysis were 0.67% and 2.42% respectively. Both errors within 5% verified the reliability of the design. Besides, the ultrasonic-assisted sawing system was selected in this paper to reveal the disadvantages of a single ultrasonic horn design that the output of tool cannot be obtained and then the optimizing cannot be performed by comparing with the expected performance. In conclusion, COMSOL integrates parametric modeling and visualization results. The app developed by COMSOL avoids repetitive labors in the design of the same type of ultrasonic horn. In-depth analysis or module redevelopment can also be carried out based on it.
